I do not know of a camera or scanner that uses 16-bit range
meaningfully. I also do not think the marginal benefit from 15
to 16 bit is much much much smaller than that from 8 to 9 bits.

I edit images in 16 bit mode even if the original file is 8
bit. This is because extra resolution is useful when resizing,
blurring, sharpening, and applying other operations to an
image. In particular, if the original image is significantly
larger than the final image size, it is often useful.
